The UK Independence Party’s freepost address has been closed after a social media campaign saw the party sent a number of inappropriate items, including human faeces.

The closure was revealed by the Ukip Bexley Twitter account, which posted a message from the Post Office that said it would no longer be able to accept items sent to the address.

The political party, which is gearing up for the European elections, had already received several inappropriate items, including bricks and litres of water, after opponents launched a campaign by posting the address online.
